TYPEWRITING MACHINE.

Application filed December 23, 1922.

To all whom it may concern Be it known that I, Lnwis G. Mrnns, a citizenof the United States, residing in Freeport, in the county of Nassau andState of New York, have invented certain new and useful Improvements inTypewriting Machines, of which the following is a specification.

This invention relates to typewriting machines in which provision ismade for regulating the margins of the printed matter. In such machinesstops are adjustably mounted on a transverse margin stop rail secured tothe carriage and movable back and forth therewith, and a centrallylocated stop lever is adapted to be engaged by the margin stops to limitthe movement of the carriage in both directions. In order that theprinted matter may be at will widened, the carriage stop lever isconnected to a key known as the margin release key by operating whichthe carriage may be released and moved to a further extent in eitherdirection to a limited extent. Such machines are also generally equippedwith a tabular rail carrying adjustable stops which are adapted at timesto engage the centrally located stop lever, the mechanism being soorganized that when desired the central stop lever may be so moved as toclear the usual margin stops on the margin stop rail when the carriageis moved back and forth, but which limits the movement of the carriageto the desired extent according to the location of the tabular stops.Ordinarily a machine of this class is provided with two adjustablemargin stops but often it is necessary to print matter having a definiteor uniform margin and also narrower matter and this involves either aseparate adjustment of the end steps or the use of an intermediate stop.

According to my invention I equip a typewriting machine with a singlecentral stop lever, two adjustable margin stops as usual and anadjustable intermediate stop, and I also employ a tabular rail equippedwith adjustable stops. Means is provided whereby the central stop levermay be so held as to allow the carriage to move to the full extentlimited by the end margin stops or to move from either end stop to theintermediate stop and' means is also provided whereby the central stoplever may be so Serial No. 608,722.

set that it will clear all of the margin stops, but will be engaged bythe tabular stops. The mechanism is so constructed that the central stoplever may be so looked as to hold it in the position to which it is setand to at willrelease it from such position when desired.

In the accompaying drawings Figure 1 is a sectional view of portions ofa typewriting machine of the Royal standard type showing my improvementsapplied thereto.

Figure 2 is a detail view of the locking devices for the central stoplever of the margin control devices.

Figure 4 shows the devices illustrated in Figure 3 in a differentposition.

The illustration is diagrammatic so far as the positions of the centralstop lever is concerned.

Figure 6 illustrates diagrammaticallyhow certain kinds of printing iscontrolled by the mechanism.

Figure 8 is an elevation showing the connections between the centralstop lever and the devices by which it is operated.

In Figure 1 I have shown only so much of a typewriting machine of theRoyal type as is necessary to indicate how my improvements are appliedthereto. Parts .of the main frame are indicatedat A. B indicates thecarriage and C the platen. The carriage is equipped with a margin stoprail D and a tabular rail. E of the usual kind and mounted in the usualway. The tabular rail carries adjustable stops 0 and the margin stoprail carries adjustable gnargin stops F and G of any suitable kind andapplied in the usual way. The margin rail is also equipped with anintermediate stop I'l similar in construction to the stops F and G buthaving its rear portion set closer to the margin rail than the stops Fand G.

The central stop lever K is pivoted between its upper and lower ends atZto a min:

- bracket L secured to the rear portion of the ill frame A. The upperportionot' thelever is properly formed and located: to engage the marginstops and the tabular stops and its.

lower portion is connected by a linkMwith the upper end of a verticallever N pivoted at n to the frame bar 0. A spring l? carried by thebracket L bears against the lever K above its pivot and tents to holdthe upper end of said lever in position to engage the end stops F and Gand the intermediate stop H. Said spring P yields to permitithe'upper-end of the lever to'be set; toclear the intermediatestop and toengage the. stops F'and G or. to clear not: onlyftheintermediate stopbut also the stops-F and G-ands to onlyengagethe tabular: stop; Thelever N is connected by a link Q to a bell crank lever R pivoted to aframes and. the upper end .otthis lever-isengaged-by :a push rodTfmounted to slideiandrto turn in the suppOrtL S'tr The 1 push rod'lT-carries interme diate its front and rear ends a laterallypro jeeting'pin i and the: front: end of the rod isaseoured "to across 'piece Vcarryingxat' opposite ends buttons 01', ogrone-ofwhmh 1s marked' rhiargin release? and theother Margin :release lock;.: The pin-t of thepushirod-extendsthrough air-angiilarslot w in a plate I secured to thesupport S and-1s.

When the pushrod T is moved forward 1n the manner indicated in Figure v 1, it may belocked in this position by turning the rod until the pin 25' engages'anol'lset part of the slot w. VVhenthe push rod is in the positionshown-Kin Figure 8the pin 1 rests against the front end of the slot 2!).The rod may be unlocked from itspositiou shown in Figure '1 byturningthe rod in the manner indicated and when thus-released the eentralstop"will be moved back: tothe position shownrin Figure-8 toengagethe-interme'dia-te margin stop H;

In order to make PIO\ '1Sl0!1';f01 tabular movement e lever N work Iemploy a key lever X pivoted at n tothe frame bar U-and-ha-ving anupwardly extending rearportion m havinga flange 00' which engages behindthe lever N. The up ward movement ot'sthe lever X is limited by a stopat? andthis lever isnormally drawn upwards by a spring a. When the keylever is depressed it moves the lever N forwards against a stop Z andthis forward causes the upper portion of the central stoplever K to bemoved to the position shown ate in Fig. 5' to engage a tabular stop 6.lt wiil theretore,be seen that when theilever X is depressed it movesthe lever: K to a greater ex tent .rearwardly, than when moved by but.-

In: l i'gurea i 5- I have shown I diagrammatr cally the relation ofthe.center stop lever, or

center stop? as itis usually-:called, with the margin stops and thetabular stopsr When the centerstop is-in the position in!v dic'atedateit will be'engaged by the right. h andlmargin' stop F and.intermediate stop H, and a transverse movement 01 th? car-1 riage willbe vthus limited and a wideilettw handjmargin obtained; hentlie;center-- stop in the position 2 the movement. of the carriagewlll-be limited by the two end stop is at e llOllQOli the stops F, andill -willbe engaged by thecenter stop but said centerstop is engaged bythe tabular stops; ln this v way as the center stop is moved to thedifferent positions, several difierent kinds of \'vo1.'k can be producedThe means shown foroperating' the/center stop is of the simplestcharacter andop erates -1nost etlic'iently; ltwill beobserved that thecenter stop lever'is operated and set by a single link connection\viththe single this lever is controlled by the push rod T andbyeitherof the tabular keys:

Thischaracteristic of the mechanism is especially useful in printinginsurance policies and the like.

It is also apparent that after printing with a narrow margin thecarriage may be quickly shifted to a position to print with a widemargin. For instance, referring to Figure 6, if after printing wide lineXYZ it is desired to print the word about (or any other word) tocommence a paragraph with a wide margin, the depression of eithertabular key will permit the carriage to be quickly shifted or jumped tothe proper position and when the tabular key is released and the buttonso, '21 properly set, the center stop may be positioned to do the desiredwork. In some cases the carriage is returned to the full length of itstravel. In such cases the tabular key may be depressed and the carriagewill jump to the position determined by the tabular stop, for instance.to the position 40 indicated in Figure 5. The work may then proceed andas other lines are written, the carriage when next returned will bearrested at the tabular stop instead of traveling its full range ofmovement, or a movement limited by the margin stops. When it is desiredto change the character of the work, the margin release key a may beactuated to release the margin release lock and the center stop may beshifted to the position shown in Figure 8 to operate between the marginstops F and H. In this way a great variety of printed matter may beproduced.
